[Serusers] How to stop SER?

Hi. I have successfully installed SER 0.9.3 in a FC3 box. I have a couple of UAs registered and they can call one each other. Now I decided to install MySQL in the same box so I tried to stop SER by: Using serctl stop and got ser.pid not found. I know it should be at /etc/var or /etc/var/ser but nothing Searched the whole box and couldn't find it. ? ? Then I tried /etc/init.d/ser stop and got "not such file or directory" Tried also /usr/local/sbin/ser stop but I got the "Listening on message. At this point as the newbie that I am I have to ask for your advice. How do I get those files in the right place and how do I stop SER? Thanks Juan
